. When the cup becomes heated,
and the spirits of wine ignited, the other lights on the stage should
be extinguished, and that of the spirit lamp shaded in some way. The
result will be, that the whole group, faces, dresses, will be of a
strong yellow tint.

COLORED LIGHTS.

Colored lights can be produced by filling globes with colored liquid,
and placing them in front of the lamps, like those we see in the
windows of the chemists' shops.

TO PRODUCE A MISTY OR VANISHING APPEARANCE TO A TABLEAU.

Several curtains of thin gauze, or common mosquito netting, made to
let down from rollers, one after another, between the audience and the
scene, will give a beautiful, misty appearance; and if a sufficient
number of curtains be unrolled, the tableau appears to vanish
entirely, allowing room for a change of scenery. Many scenes should
have one thickness of muslin before them, which serves to blend the
colors, and gives a finish to the picture. The gauze must be carefully
managed, as the disclosure of a ragged edge will dispel all the
illusion.

TO PRODUCE SOUNDS LIKE FALLING RAIN.

Procure a box six feet long, one foot wide, and one deep. Cover the
bottom with small pegs of wood one inch high, and inserted two inches
apart. Place a quart of dried peas at one end of the box; then raise
that end quite slowly, allowing the peas to roll gradually down to the
lower part of the box. The sound they produce in striking against the
pegs imitates to perfection the falling of rain. The sound can be
continued for any length of time by raising alternately each end of
the box.

TO PRODUCE SOUNDS LIKE DISTANT FIRING OF ARTILLERY.

Suspend a large sheet of Russia iron by means of a rope, and strike it
in the centre with a heavy drumstick. At a short distance, the sound
resembles the booming of heavy artillery.

TO PRODUCE SOUND TO RESEMBLE THUNDER.

Hold a large sheet of Russia iron at one end and commence shaking it
very slowly. It will give out a low, rumbling sound, which can be
gradually increased in power. Graduate the sounds from heavy peals to
the first starting point, then discontinue the shaking for a few
seconds, and repeat the variety of changes as long as is necessary.

TO IMITATE THE FIRE ALARM BELL.

Suspend to a wooden frame two pieces of steel two inches square and
three feet long. Select pieces that will give out different tones, and
strike them alternately with an iron hammer. They will sound much
